Pentraxins family of proteins acquired the name from their ability to form pentameric (or decameric) structures formed by non-covalent interactions. C-reactive protein (CRP or PTX1; mature chain 206 aa; chromosome 1q21-23) nonglycosylated, ~24kD monomer and ~118kD pentamer) is a ubiquitous protein found in both vertebrates and invertebrates. Originally CRP was defined as a substance, observed in the plasma of patients with acute infections, that reacted with the C polysaccharide of the Pneumococcus. It is one of the plasma proteins that are called acute phase reactants because of a pronounced rise in concentration after tissue injury or inflammation. In the case of CRP the rise may be 1000-fold or more. CRP is composed of 5 identical, 21,500MW subunits. It is detectable on the surface of about 4% of normal peripheral blood lymphocytes. Acute phase reactant CRP is produced in the liver. Those cells produce CRP detectable on lymphocytes.
